photosynthesis and cellular respiration Flashcards
photosynthesis def.
process by which plants use energy from the sun to make their own food. (glucose)
equation for photosynthesis
carbon dioxide + water + light makes glucose and oxygen
CO2 + H2O + Light makes C6H12O6 and O2
autotroph def.
organisms that use the suns energy to make its own food
chlorophyll def.
the pigment in plants that absorbs all light except green
chloroplast def.
organelle found in plant cells, it contains chlorophyll for photosynthesis
do all plants contain chlorophyll?
yes
what part of the plant contains the highest chlorophyll concentration>
the leaves
stomata def. (important)
opening the leaf through which water and gasses are exchanged
guard cells def. (important)
cells surrounding the stomata that control its opening and closing
describe light reactions
light dependant reactions, occurs in the grana of chloroplasts, produces oxygen
describe dark reactions
light dependant reactions, occurs in the stroma of the chloroplast,produces glucose
cellular respiration def.
the release of energy that is stored in food.
whats cells do cellular respiration
every cell. (essential for daily living)
where does cellular respiration take place
mitochondria
what is the purpose of cellular respiration
to make atp - atp provides the cell with energy
what does atp stand for
adenosine triphosphate
how is energy brought out
breaking of chemical bonds
define aerobic
needs energy
define anaerobic
does not need energy
what is the aerobic respiration equation?
glucose + oxygen makes carbon dioxide, water, and atp
c6h12o2 + O2 makes co2, h2o, and 36 atp
what is an example of an organism that live in anaerobic environments
yeast, bacteria
what is not produced after glycolysis for organisms that live in anaerobic environments
atp
fermentation def.
process that takes place after glycolysis (part of anaerobic respiration
alcoholic fermentation equation
glycolysis (makes 2 atp) goes to fermentation and makes carbon dioxide and ethanol/alcohol
does alcoholic happen in humans
no we would be drunk all the time
lactic acid fermentation equation
glycolysis (makes 2 atp) goes to fermentation and makes lactic acid
glycolysis def.
the break down of glucose from enzymes to make energy
when does photosynthesis occur?
in the presence of light only
when does cellular respiration occur
in the light or dark
what are the inputs of photosynthesis
sunlight water and carbon dioxide`
what are the inputs of cellular respiration
oxygen and glucose
what is the outputs of photosynthesis
oxygen glucose
what is the outputs of cellular respiration
carbon dioxide water and energy
what type of cell does photosynthesis occur in
plant cell
where does photosynthesis take place
chloroplast
what type of cell does cellular respiration occur in
animal, bacteria, plant cells
what is the energy result for photosynthesis
chemical energy (glucose)
what is the equation for cellular respiration
glucose + energy makes atp, carbon dioxide, and water
what is the xylem
carries water and mineral up from the roots of the plant
what is the phloem
carries sugars (nutrients) away from the leaf to areas where the plant is growing
what are the reactants of aerobic respiration
glucos+oxygen
what are the products of aerobic respiration
atp+carbon dioxide+water
what are the reactants of alcoholic fermentation
glucose+fructose
what are the products of alcoholic fermentation
ethinol/alchohol + carbon dioxide
what are the reactants of lactic acid fermentation
glucose
what are the products of lactic fermentation
lactic acid and energy
how much atp s produced during aerobic respiration
30 to 32
how much atp is produced during anaerobic respiration
2
what are two possible products of anaerobic respiration
ethanol/lactic acid fermentation
do ethanol/lactic acid ferm need energy
no
where does aerobic respiration take place
mitochondria
where does anaerobic respiration take place
cytoplasm
